How can I list all files but not directories in a given directory and show the inode-numbers.

Something like ls -li | grep ^- does not work since the inode number is shown in the beginning of the line.

There are multiple solutions. Assuming you do not have a filename starting with -

ls -li | grep " -" ls -li | awk '/ -/'

If a directory contains -, it can be fixed by

ls -li | grep "[0-9][0-9]* -" ls -li | awk '$2 ~ "-.{9}"'

You could use find:

find . -maxdepth 1 -type f -exec ls -li '{}' \;

or, to get ls-like output:

find . -maxdepth 1 -type f -printf '%i %M %n %u %g %kK %Tc %p\n'

Parsing ls is a bad idea since it can often lead to trouble.

If you really want to use ls directly, you could do this:

ls -li | gawk '$2!~/d/'

  • You might want to use + instead of \; in your first example (if your version of find supports is) so as not to fork too much on ls. Might also want to add \! -name '.*' so as not to list hidden files. Commented Jul 6, 2013 at 14:36

    Oh, and if you want to parse the output of ls, and if your ls version supports the -p option, you can ls -lip | grep -v '/$' Commented Jul 6, 2013 at 14:49
  • @gniourf_gniourf since the + is not always available and we are only running ls which is not too hard on the machine I don't think it is worth it. As for hidden files, I consider listing them a feature not a bug :). Commented Jul 6, 2013 at 14:49
  • @student I rejected your edit because the -execdir option, while great, isn't portable and I don't want this answer to be specific to GNU find. Note that in my rejection message I incorrectly claimed the + is also not portable, but that is wrong. The + is in POSIX, but -execdir is not. Commented Mar 20 at 10:21

Another find alternative:

find -maxdepth 1 -type f -printf "%i %p\n"

Or yet another:

find -maxdepth 1 -type f -ls

  • You might want to use maxdepth 1 to mimic ls. Otherwise, this will find all files in all subfolders recursively. Commented Jul 6, 2013 at 14:31

Here's an alternative way using the commands tree and grep. Grep is used to filter out the directory entries:

$ tree --inodes -f -F|grep -v "/$"

Example

$ tree --inodes -f -F|grep -v "/$"|less . |-- [10370679] ./a |-- [10359494] ./a.bash* | |-- [10359495] ./alsa/alsa-info.sh* | `-- [10370145] ./alsa/alsa-info.txt.v8hSmCT2Rf | | | |-- [11147371] ./apps/apache-maven-2.0.9/bin/m2* | | | |-- [11147367] ./apps/apache-maven-2.0.9/bin/m2.bat | | | |-- [11147368] ./apps/apache-maven-2.0.9/bin/m2.conf | | | |-- [11147372] ./apps/apache-maven-2.0.9/bin/mvn* | | | |-- [11147369] ./apps/apache-maven-2.0.9/bin/mvn.bat | | | |-- [11147373] ./apps/apache-maven-2.0.9/bin/mvnDebug* | | | `-- [11147370] ./apps/apache-maven-2.0.9/bin/mvnDebug.bat | | | `-- [11147378] ./apps/apache-maven-2.0.9/boot/classworlds-1.1.jar | | | `-- [11147374] ./apps/apache-maven-2.0.9/conf/settings.xml | | | `-- [11147376] ./apps/apache-maven-2.0.9/lib/maven-2.0.9-uber.jar | | |-- [11147363] ./apps/apache-maven-2.0.9/LICENSE.txt | | |-- [11147364] ./apps/apache-maven-2.0.9/NOTICE.txt | | `-- [11147365] ./apps/apache-maven-2.0.9/README.txt

The above incorporates the directory hierarchy into the lines for each file, and also makes use of the -F switch so that tree appends a trailing / to each line that's a directory. Utilizing that feature, we're able to grab any lines that now have this trailing / and omit them.
